Abstract
A shroud for use with a turbine blade is disclosed wherein the shroud provides at least one knife edge with at least one tooth for cutting a groove in a compliant rub strip that minimizes wear on the knife edge. The tooth is positioned along the knife edge inward of the ends of the knife edge and a distance from an airfoil stackline such that the moment created by the tooth mass and its effect on shroud bending stress is significantly reduced, thereby resulting in increased turbine blade durability.
